my impression is that the refurbishment is done on the whole building every so often, but that if one appartment gets thrashed or has really bad students that break everthing in a particular appartment, the management company will pay for that. The only thing is there seems to be a few of them for sale now so they are not exactly snapped up immediately, you have to be a cash buyer. Therefore I think you need to be prepared to lock up your money for a long time, on the other hand though you are only locking away 60K not 250K etc that you would be by buying a conventional house.
